' A triangular piece G is placed and secured' e time not to nterferewith the f of pasteboard orw'ood;n against thev inner surface of each end piece F ot the casingas- 1 shown in Figs. 2 and 3, and on the edgesroff said pieces F- the end -parts of two. polishedl prisms H and J are rested.- i p The prisms in of a triangle, that the base of the casing pieces G and the other p to hold the p'rism J in place M. is inserted between thepnsm plain glass G to hold the prism-Hr A wedge H and the inplace. y Y i. To use the optical toy the same isplaced in: 801' front to the eyes in such a manner that they" observercan look through the openings B; the open side and top'ot the casingfacingthe object to be-viewed.

In an optical toy, the combination with a casing having sight openings in one wall and having part of its top uncoveredfot triangular pieces secured to the inner faces of the ends of the casings, two prisms, each triangular in cross section, rested upon the edges of said triangular pieces the baseot' one prism being along the apex of the other prism, substantially as herein shown and described.

4. In au optical toy, the combination with a casing provided with sight openings in one wall, of a plain piece of glass placed against the inner surface of the wall provided with said openings, two prisms held at an angle to each other within said casing, and a wedge interposed between one of said prisms and the piece of plain glass, substantially as, herein shown and described.

5. In an optical toy, the combination with a. casing provided withl sight openings in one wall and provided with a top of about half the width of the casing and connected with the top of the wall having the openings, of two prisms held at an inclination to each other in said casing and a flange on the free edge of said top, the bottom edge of said flange resting against the top parts of the prisms, substantially as herein shown and described.
